Current facilities were intervened to meet standards
Consulting, Project Management
The Municipality of Manta has a pond system for the treatment of wastewater generated by its population, consisting of four anaerobic ponds, four optional and four for maturation. The current system has no pre-treatment and its contamination reduction yield is under the standards. For this reason, it was necessary to intervene on the existing facilities, adapting to the new flow process and a greater requirement for levels of purification, this is why a tertiary treatment of effluent was necessary. Processing capacity 50,000 m3/day.
Primary treatment: Removal of fine, tumbling, degreasing and longitudinal ventilation. (2 lines) Secondary treatment: UASB anaerobic reactor (2 lines) and facultative pond existing No. 1. The basin is used as it is now. Before commissioning it was drained and emptied of sludge. Tertiary Treatment: Via maturation ponds existing restore 1, 2, 3 and 4. Was then added a process of coagulationflocculation and filtration through granular elements, in two rows and, finally, a disinfection process with UV rays.
In addition, a pipeline was built from the WWTP to the refinery to 12 km., a pumping station and a 3.5 km long pipeline.
